Triplon band splitting and topologically protected edge states in the dimerized antiferromagnet
Topological edge states can emerge not only in a fermionic electron system but also in a bosonic system. Here, Nawa et al. report topologically nontrivial triplon bands in a two-dimensional dimerized quantum antiferromagnet Ba2CuSi2O6Cl2, suggesting a bosonic realization of the coupled Su-Schrieffer...
